Selection of Lubricants for Dies

During forging, Die Lubricants play a vital role. This article shall help you in selecting good and reliable lubricants for dies when forging Stainless Steel, Aluminum Alloy, Copper, Copper Alloy, Carbon, and Alloy Steel Forgings

STAINLESS STEEL:Oil and graphite mixture are mostly used but oil should be free from lead and sulphur gas is also used as a lubricant in press forging of stainless steels.

ALUMINUM ALLOY: Graphite mixed with water but if the material flow is a problem in the narrow ribs or cavities then soap is added to the graphite mixture.

COPPER AND COPPER ALLOY: Graphite mixed with water is most widely used as lubricant in cu and cu alloy forgings.

CARBON AND STEEL: Graphite mixed with water for deep cavities and narrow ribs, while furnace oil used for simple impression dies.
